The Election Commission on Monday concluded the hearing on an office of profit case against 21 Aam Aadmi Party MLAs who were appointed parliamentary secretaries by Chief Minister Arvind Kejriwal. The controversy erupted after Kejriwal made appointments in March 2015 and his government passed an amendment to the Delhi Members of Legislative Assembly (Removal of Disqualification) Act, 1997, in June 2015 to exempt the post of parliamentary secretary from the definition of office of profit with retrospective effect. The 21 AAP lawmakers are facing prospects of disqualification in the order expected in the coming days. While AAP said after the Delhi High Court ruling the case should be dropped against them, the petitioner, Prashant Patel, maintained that the court order should have no bearing on the case being heard by the EC. On September 8, the Delhi High Court had set aside the appointment of 21 party MLAs as parliamentary secretaries. The court had said the order to appoint them as parliamentary secretaries was given without the concurrence of the Lieutenant Governor.\u00a0 A bench of Chief Justice G Rohini and Justice Sangita Dhingra Sehgal had set aside the March 13, 2015 order after the counsel appearing for the Delhi government "conceded" that it was issued without taking concurrence or views of the LG. The poll panel had heard the case on December 16 last before it got busy with assembly elections in five states. The development comes on a day when AAP suffered a massive setback after one of his MLAs joined BJP ahead of the crucial MCD polls. MLA Ved Parkash today resigned from the party and the Delhi assembly to join the BJP, alleging the Arvind Kejriwal government has "failed" to deliver on poll promises. The move is big booster for Bhartiya Janata Party as elections to the three municipal corporations of Delhi (MCDs) are scheduled to be held on April 23.
